Marine battery charger for 12V systems

The Guest 2708AAll is a 12V on-board battery charger designed for flooded and AGM lead-acid batteries. It provides a single bank with a 5A output for dedicated charging and control. The unit suits boat owners who need automatic, multi-stage charging for one battery bank.

Input range and environmental limits

The charger accepts 90-135V AC at 50/60Hz for flexible shore-power connection. It is rated IP67 for 100 percent waterproof and shock-resistant operation in fresh and saltwater environments. The high-frequency digital technology reduces weight by up to 40 percent compared to earlier designs.

Replaces manual or non-waterproof chargers

This model upgrades from chargers lacking automatic 5-stage performance charging or per-bank sensing. The jump is worth it when you need built-in reverse polarity, over-current, over-voltage, over-temperature and ignition protection with in-line fuses. It is not for installations requiring multiple banks or higher amperage per bank.

Questions about this item

Should I choose the 5-amp single-bank model or a higher-amp multi-bank charger?

The 2708A delivers 5 amps to one 12-volt bank; pick it when you only need to maintain one flooded or AGM battery.

What does the 5-amp rating mean when the charger is connected to my battery?

It supplies up to 5 amps through a fully automatic 5-stage cycle with dedicated sensing and an expanded LED status monitor per bank.

What input voltage range does the 120-volt AC specification actually cover?

The unit accepts 90 to 135 volts AC at 50 or 60 hertz, so it runs on standard North American shore power.
